Detailed Description

!

BLAS Level 2 API

\details
xGEMV_BATCHED performs a batch of matrix-vector operations

    y_i := alphaA_ix_i    + betay_i,   or
    y_i := alphaA_iTx_i + betay_i,   or
    y_i := alphaA_iHx_i + betay_i,

where (A_i, x_i, y_i) is the i-th instance of the batch.
alpha and beta are scalars, x_i and y_i are vectors and A_i is an
m by n matrix, for i = 1, ..., batch_count.

@param[in]
handle      [rocblas_handle]
            handle to the rocblas library context queue.
@param[in]
trans       [rocblas_operation]
            indicates whether matrices A_i are tranposed (conjugated) or not
@param[in]
m           [rocblas_int]
            number of rows of each matrix A_i
@param[in]
n           [rocblas_int]
            number of columns of each matrix A_i
@param[in]
alpha       device pointer or host pointer to scalar alpha.
@param[in]
A           device array of device pointers storing each matrix A_i.
@param[in]
lda         [rocblas_int]
            specifies the leading dimension of each matrix A_i.
@param[in]
x           device array of device pointers storing each vector x_i.
@param[in]
incx        [rocblas_int]
            specifies the increment for the elements of each vector x_i.
@param[in]
beta        device pointer or host pointer to scalar beta.
@param[inout]
y           device array of device pointers storing each vector y_i.
@param[in]
incy        [rocblas_int]
            specifies the increment for the elements of each vector y_i.
@param[in]
batch_count [rocblas_int]
            number of instances in the batch
